It’s kind of funny. The truck took 2 years to design, and another 2 years to assemble the 1,000+ components together, but people seem to be most interested in the composting toilet and the grey water drain!
Yes – it smells bad. We treat it every once in a while and rinse the tanks, but I won’t lie to you. If we’re parked stationary and you are standing within 3 ft of the drain, it smells a little.
As for corrosion, I haven’t seen any. My assumption was that the exhaust pipe was made of stainless steel, and that’s why, but I may be way off on that.
